Description Jon Senior 2011-05-16 08:14:21 UTC
----- Note ------
Problem is created when using Samsung Unified Driver to provide printer driver for ML-1640 (and presumably other) printers.

SELinux is preventing /usr/sbin/cupsd from read, open access on the file /usr/lib/cups/filter/rastertosamsungspl.

*****  Plugin restorecon (99.5 confidence) suggests  *************************

If you want to fix the label. 
/usr/lib/cups/filter/rastertosamsungspl default label should be bin_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /usr/lib/cups/filter/rastertosamsungspl

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If you believe that cupsd should be allowed read open access on the rastertosamsungspl file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep cupsd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
